[Check_mk (english)] FW: HTTP Active Check check

Nicholson_Charles_RI · October 29, 2015, 7:37pm

I'm trying to setup OMD with Check _MK and every attempt I make to contact a known website, internal or external fails with a connection_refused, unable to open TCP socket message. I need to be able to complete HTTP checks similar to what I have already in Nagios with curl commands and find results. I also need to test the check via server command line. Can you explain what is going on? Thank you.

Hi Charles,

at first: knowing your used OMD and Check_MK version could help debugging.

Generally you can check what’s going on with active http checks by navigating to your terminal console, become OMD siteuser and execute this (according to your provided data):

~/lib/nagios/plugins/check_http -I PUTYOURHOSTIPHERE -u ‘www.google.com’ --ssl -v

…param “-v” is for debugging output. If this does not work try the command without “–ssl”.

HTH,

Marcel

Hi Charles,

The -u option (url) is used to specify the url, not the hostname.
The command should be something like this:

~/lib/nagios/plugins/check_http -H 'www.google.com ’ -I
PUTYOURHOSTIPHERE -u ‘/’ --ssl

-H is used to specify the host header (vhost in WATO).
-u is used to spedify the url to reach (i.e. / or

/search?q=whatever+query)

Regards,

Paul

Hi Paul,

thanks for clarification - it’s somewhat late and I should go to bed, did not recognize the -u param issue

Regards,
